The following shows a graph of the energy changes taking place as a chemical reaction progresses. If an enzyme is added, which arrow's magnitude will change? Will it decrease or increase?

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

what's the question ?

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
